Abstract(s)
A doença periodontal é uma doença infeciosa associada a bactérias específicas e caracterizada pela inflamação dos tecidos de suporte dos dentes e destruição progressiva do osso alveolar e dos tecidos adjacentes.
A ocorrência e progressão da doença periodontal como doença multifatorial, de etiologia bacteriana é influenciada por outros fatores como o hospedeiro, determinados fatores de risco (como, por exemplo, o tabaco e o álcool) e o tempo. Os fatores derivados do hospedeiro podem ser influenciados por fatores genéticos, hormonais e nutricionais. Entre os fatores nutricionais, a vitamina C ou ácido ascórbico (AA) tem assumido um papel importante relativamente à doença periodontal.
A formação e a regeneração do periodonto dependem do colagénio. A falta de vitamina C será responsável por um defeito na síntese de colagénio tecidual. Na periodontite, observa-se stress oxidativo e a vitamina C, fornecida pelos alimentos, ajuda a combater esse stress.
O ser humano não é capaz de sintetizar endogenamente esta vitamina para suprir as suas necessidades e a suplementação dietética de ácido ascórbico pode ser considerada como um complemento à rotina de terapia periodontal.
Sempre que possível, deve haver colaboração entre médicos, médicos dentistas e nutricionistas para que, através do conhecimento e compreensão de causas e efeitos de uma má nutrição, poderem desenvolver estratégias positivas de prevenção e tratamento de estados nutricionais deficitários.
Periodontal disease is an infectious disease associated with specific bacteria and characterised by the inflammation of the teeth’s’ supporting tissues as well as the progressive destruction of the alveolar bone and the adjacent tissues. The occurrence and progression of periodontal disease as a multifactorial disease of bacterial aetiology is influenced by other factors such as the host, certain risk factors (as, for instance, smoking and alcohol) and time. The factors deriving from the host may be influenced by genetic, hormonal and nutritional factors. Amongst the nutritional factors, vitamin C or ascorbic acid (AA) has assumed a relatively important role in relation with periodontal disease. The formation and regeneration of the periodontium depends on collagen. The lack of vitamin C will be responsible for a defect on the synthesis of collagen tissue. In periodontitis, oxidative stress is observed and vitamin C, supplied through nourishment, helps to fight off that stress. The human being is not capable to endogenously synthesize this vitamin in order to meet the necessities and the dietary supplementation of ascorbic acid can be considered as a complement to the periodontal therapy routine. Whenever possible, there must be collaboration between physicians, dentists and nutritionists so that, through the knowledge and understanding of the causes and effects of a bad nutrition, they might develop positive strategies of prevention and treatment of deficit nutritional states.
